Quality-wise? I am not so sure the Japanese have a such big edge any more. American automobiles have been right "up there" in quality for years now. I think we are largely dealing with perceptions that have carried over from when there was a big difference.
True, but then again the big three did this to themselves as well by going on the cheap through the 1980's. It was at that time that they began to shut down American production plants in mass during and shipping work off to Mexico (among others), all during a time when they had record profits. The dip in quality they experienced during that time built in a huge public perception that Detroit simply has not been able to recover from. It also opened the way for other auto manufactures to become more competitive during that time.
Sure the legacy costs have been a tremendous burden to these companies, but I think they are part of something like a triple death blow. You also have the current financial situation (as well as fuel situation) plus their own poor strategy in assessing the market.
Anybody remember Chevy's "An American R(E)volution". Add this Dodge Ramm challenge onto a list of short sighted, completely ridiculous, marketing plan that will simply not pull them through. Sure this kind of crap could be part of their portfolio, but they made it just about all of it and are going to reap the rewards.
In regards to the displaced people, I think we should do what we usually do. Help people who are displaced find new work rather than bailing out failing companies that do not work. The phrase 'to big to fail' is reflective of a much bigger problem in America IMO.
